Prior to the evaluation of the studied catalyst samples, the blank test in the absence of the catalyst sample was carried out in the range of 100-500[degrees]C and GHSV = 4000 mL [h.sup.-1] [g.sup.-1] (STP).
Quartz tube reactor, (2011) 0.2 g (40-60 mesh catalyst was packed; GHSV: 30,000 [mLh.sup.-1] [g.sup.-1], or 60,000 [mLh.sup.-1] [g.sup.-1] Chen et al.
For a micro-converter with GHSV equal to 60 000 [h.sup.-1] the value of the parameter n of the order of 2.1 is obtained.
Caption: FIGURE 8: Catalytic activity in CO oxidation over (a) calcined Au-Fe and (b) [H.sub.2]-treated Au-Fe nanocomposite catalysts (reaction conditions: weight of catalyst 0.5 g; total flow rate 1000 mL [min.sup.-1]; feed composition 100 ppm CO/air; GHSV = 120,000 mL [g.sup.-1] [h.sup.-1]).
The experimental condition are similar: T = 800[degrees]C, GHSV = 60 000 [h.sup.-1], 1C[H.sub.4]/1C[O.sub.2]/3[N.sub.2] (Roh et al., 2002b) and T = 800[degrees]C, GHSV = 24 000 [h.sup.-1], 1C[H.sup.4]/1C[O.sup.2] (Li et al., 2004; Li et al., 2003).
The SCR activity measurements were carried out in a fixed-bed reactor at 60-160[degrees]C containing 4g catalyst with a gas hourly space velocity (GHSV) of 24, 000 [h.sup.-1].
The catalytic oxidation activities of Hg0 over Fe2O3-ATP were carried out in a fixed-bed flow reactor system under a total flow of 1L/min and a gas hourly space velocity(GHSV) of about 37700h-1.
The total gas flow rate was maintained at 21.2 L/min, resulting a Gas Hourly Space Velocity of 30,000 [h.sup.-1] (GHSV =30,000 [h.sup.-1]).
The experimental GHSV is 40,000 [h.sup.-1], which is close to the real diesel engine exhaust.
The catalytic oxidation activities of Hg0 over ATP@Fe2O3 composite were carried out in a fixed- bed flow reactor system under a total flow of 1 L min-1 and a gas hourly space velocity (GHSV) of about 37700 h-1.
Mn/TNTs-NE showed a good SCR activity even though the activity tests were conducted with a high GHSV at about 100,000 [h.sup.-1].
Their study focused on the effects of three parameters including gas hourly space velocity (GHSV), operating temperatures and ammonia content on the NOx conversion (N[H.sub.3]/NOx ratio); their work was based on improving NOx reduction through the optimisation and control of operation parameters (e.g.
